Clinic
- Upper Motor Neuron Pathways are first-order neurons, responsible for carrying signals that Initiate / Modulate / Coordinate movement.
- The major UMN tract that initiates voluntary movement is the pyramidal tract
- UMN disease is a wide and varied collection of disease which have UMN involvement in common
Entities
Upper motor neuron entities are
- Muscle Weakness / Paralysis
- Incoordination: Decreased motor control including Speed, Accuracy and Dexterity
- Hypotonia or Hypertonia / Spasm
- Decreased endurance
- Hyper reflexia: Exaggerated deep tendon reflexes
- Spasticity
- Clonus
- Reappearance of primitive reflexes, such as the extensor plantar response (Babinski sign)

Note
- UMN tract is initiating and coordinating movement.
- So I suggest The rubric "Spastic paralysis" for problem in initiating muscular movement
- And also the rubric "Incoordination" for problem in coordination
